Access sibling service from docker container's service

Question

I run Node image based docker container (Docker quickstart terminal from Windows)

FROM node:7.8.0
ENV NPM_CONFIG_LOGLEVEL warn

VOLUME /tmp
#copy server sour         


        

Answer 1

There are few things you can do here

Let other container run on network of other container

docker run --net container:<id> MyDockerImage

Now your mongodb will be accessible on localhost. But the port needs to be exposed in the container whose network is used

Create network yourself and use it

docker network create myapps

docker run --name mongodb_service --net myapps mongodb
docker run -p 3000-3009:3000-3009 --net myapps MyDockerImage

Now inside your MyDockerImage, mongodb can be reached at mongodb_service

Use docker compose

You can use docker-compose to run both of them as a composition

version: '3'
services:
  mongo: 
    image: mongodb
  app:
    build:
      context: .
    ports:
      - "3000-3009:3000-3009"

And now in app mongodb will be reachable with name mongo
